Description
technical field [0001] The invention relates to the technical field of civil engineering sensors, in particular to an anti-corrosion intelligent aggregate. Background technique [0002] In recent years, with the continuous deepening of the research on piezoelectric ceramic smart materials, its application in civil and water engineering has become increasingly widespread, especially in the application of structural damage identification and health monitoring technology, which has achieved fruitful results. [0003] Piezoelectric-based sensors are widely used in structural health detection in civil engineering, such as civil engineering concrete crack detection, interface damage detection, and damage imaging. However, the traditional marble and concrete-coated piezoelectric smart aggregate sensor will be corroded by chloride ions during long-term service. Long-term use leads to the attenuation of sensor performance, resulting in a decrease in sensor accuracy. [0004] In ord...
